In the frame of the material research for future fusion reactors, the construction of a simplified facility of IFMIF*, the so-called IFMIF/DONES** (Demo-Oriented Neutron Early Source), to generate sufficient material damage for the new design of DEMO . DONES will be a 40 MeV, 125 mA deuteron accelerator. The 5 MW beam will impact in a lithium flow target to yield a neutron source The detailed design of the DONES accelerator is being designed within EUROFUSION-WPENS project. One of the most critical tasks of the accelerator will be to identify the layout of beam diagnostics along the accelerator. This instrumentation must guarantee the high availability of the whole accelerator system and the beam characteristics and machine protection. This contribution will describe the beam diagnostics selected along the accelerator, focusing in the High Energy Beam Transport line, in charge of shaping the beam down to the high power target. The main open questions will be analyzed and the path to obtain the detailed design by the end of the project detailed.

  This research aims to design and develop an elec-tron linear accelerator system and beam diagnostic instruments for natural rubber and polymer research at the Plasma and Beam Physics Research Facility, Chiang Mai University, Thailand. The accelerator con-sists of a DC thermionic electron gun and an S-band standing-wave linac. The system can produce electron beams with the energy range of 0.5 to 4 MeV for the pulse repetition rate of 30 to 200 Hz and the pulse duration of 4 μs. Commissioning of the accelerator system and development of beam diagnostic instru-ments to measure electron beam energy, electron pulse current and electron dose are underway. This contribu-tion presents and discusses on the RF commissioning progress as well as status of design and construction of the beam diagnostic system.

  Funding: This project has received funding from the European Union's Seventh Framework Programme for research, technological development and demonstration under grant agreement no 289485.
A comprehensive set of beam diagnostics is key to the successful operation and optimization of essentially any accelerator. The oPAC project received 6 M€ of funding within the EU's 7th Framework Programme. This has allowed to successfully train 23 Fellows since 2011. The network joins more than 40 institutions from all around the world, including research centers, universities and private companies. One of the project's largest work packages covers research in beam diagnostics. This includes advanced instrumentation for synchrotron light sources and medical accelerators, enhanced beam loss monitoring technologies, ultra-low emittance beam size diagnostics, diagnostics for high intensity beams, as well as the development of electronics for beam position monitors. This contribution presents an overview of the research outcomes from the diagnostics work package and the demonstrated performance of each monitor. It also shows how collaborative research helps achieving beyond state-of-the-art solutions and acts as an ideal basis for researcher training. Finally, an overview of the scientific events the network has been organizing for the wider accelerator community is given.

  I.P.H.I. is a High Intensity Proton Injector (C.N.R.S/I.N.2P.3; C.E.A./Irfu and C.E.R.N. collaboration) located at Saclay and now on operation. An E.C.R. source produces a 100 keV, 100 mA C.W. proton beams which will be accelerated at 3 MeV by a 4 vanes R.F.Q. operating at 352.2 MHz. Finally, a High Energy Beam Transport Line (H.E.B.T.) delivers the beam to a beam stopper. The HEBT is equipped with appropriate beam diagnostics to carry beam current, centroid beam transverse position, transverse beam profiles, beam energy and energy spread measurements for the commissioning of I.P.H.I. These beam diagnostics operate under both pulsed and C.W. operation. However transverse beam profile measurements are acquired under low duty factor pulsed beam operation using a slow wire scanner. The beam instrumentation of the H.E.B.T. is reviewed and the first measurements at 3 MeV are described.

TUPG57 5 MeV Beam Diagnostics at the Mainz Energy-Recovering Superconducting Accelerator MESA diagnostics, cavity, dipole, detector 479

  Within the next few years a new energy recovering superconducting electron accelerator will be built at the institute for nuclear physics in Mainz. To adjust the properties of the beam correctly to the first acceleration in the superconducting cavities, a high resolution longitudinal beam diagnosis is required at the 5 MeV injection arc. The system employs two 90-degree vertical deflection dipoles to achieve an energy resolution of 500 eV and a phase resolution of 60 micrometers. As a second challenge the transverse emittance measurements will take place at full beam current. This demands an extremely heat resistant diagnosis system, realized by a method similar to flying wire.
